AI Thread Summary
Tapping into the Earth's magnetosphere for power generation is deemed impractical due to the principles of Faraday's Induction Law, which requires a change in magnetic field magnitude or polarity to generate voltage. The Earth's magnetic field only flips approximately every 200,000 years, making it an unreliable source for consistent energy. Some participants suggested unconventional methods, like using high-altitude weather balloons with wires, but acknowledged the lack of practical application. Overall, the discussion highlights the challenges and theoretical limitations of harnessing Earth's magnetic power. Exploiting the magnetosphere for energy remains largely unfeasible.

Is it possible to tap into the Magnetosphere to generate power? I mean the core of the Earth is in fact a giant generator, so why can't (or aren't) we exploiting this potential?

We can't exploit it. Based on the Faraday Induction Law, there has to be a change in the magnetic field magnitude or polarity to get a voltage out. The Earth's magnetic field flips about once every 200,000 years. See

Don't wait for it.

So you're saying that there is no magnetic flux? I did not know that!

I attempted to state that the magnetosphere's magnetic flux did/does/won't change for ~200,000 years.

How about some big high altitude weather balloons dragging long wires behind them...

I have no practical way of exploiting this. And the airline industry would love me. Just a strange thought. But theoretically we could get a voltage diff in the wire... I think.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
